I am currently running a project and I want to send the measurements of 3-4 Arduino UNO WiFi with Hum&Temp sensors to a MySQL database in my Raspberry Pi3.
I have already done the serial part. I can see direct from my Raspberry's serial port, the console prints of my Arduino. But at the end I would like to recieve all these data wirelessly so I can place the Arduinos in different spots in the lab.
Can anyone help me please??
Thank you in advance!!
